Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a coagulation analyzer reaction cup that is easy to handle and place. Background Technology

[0002] Coagulation analyzers, as key equipment in clinical laboratory testing for assessing blood coagulation function, are widely used in preoperative coagulation status screening, diagnosis of hemorrhagic diseases, and monitoring of anticoagulation therapy. The accuracy of their test results directly affects the rationality of clinical diagnosis and treatment decisions. Reaction cups, as the core consumables of coagulation analyzers, are the core carriers for holding blood samples and reaction reagents, completing the coagulation reaction, and acquiring optical / electrical signals. Their structural design not only affects the ease of operation for medical staff but is also closely related to the repeatability and reliability of test results.

[0003] Currently, most coagulation analyzer reaction cups on the market adopt an integrated cylindrical thin-walled transparent structure with a smooth outer wall and lack dedicated support or positioning mechanisms. This presents significant drawbacks in actual clinical use: Firstly, due to the lack of positioning reference, it is difficult for medical staff to ensure the coaxiality of the cup's axis with the instrument's optical detection channel and temperature control module when placing the reaction cup into the coagulation analyzer's testing station. This can easily lead to cup tilting or offset, resulting in obstructed optical path and uneven temperature control, thus causing deviations in test results. This is particularly significant for optical coagulation tests that rely on changes in optical density, reducing test repeatability. Secondly, the smooth outer wall of the cup makes handling difficult. Especially when medical staff are wearing sterile gloves, insufficient friction causes fingers to slip on the cup wall, increasing the difficulty of handling and potentially causing the reaction cup to slip, resulting in spillage of blood samples and reagents. This wastes testing consumables and may contaminate the operating table and instrument surface, increasing the risk of cross-infection. Utility Model Content

[0004] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a coagulation analyzer reaction cup that is easy to handle and place, effectively solving the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coagulation analyzer reaction cup that is easy to pick up and put down, comprising a cup body, wherein a support mechanism is provided on the outside of the cup body;

[0006] The support mechanism includes an annular seat, which is fixedly sleeved on the outside of the cup body. An arc-shaped hole is opened on the top of the annular seat, and two positioning grooves are opened on the top of the annular seat. Four rectangular holes arranged in a ring array are opened on the bottom of the annular seat, and guide rods are fixedly connected to the inner walls of the rectangular holes.

[0007] Preferably, the annular seat has a cavity inside, and four lead screws arranged in an annular array are rotatably connected to the inner wall of the cavity. A first bevel gear is fixedly sleeved on the outside of the lead screws, and a slider is threaded to the outside of the lead screws. The slider is slidably disposed inside the rectangular hole and sleeved on the outside of the guide rod. A support plate is fixedly connected below the slider, and a groove is formed on one side of the support plate.

[0008] The cavity provides a sealed protection for the transmission components, preventing contamination or damage; the guide rod restricts the rotation of the slider, ensuring that the support plate is precisely adjusted along a straight line.

[0009] Preferably, an annular block is rotatably connected to the inner wall of the cavity, a second bevel gear is fixedly connected to one side of the annular block, the second bevel gear meshes with four first bevel gears, and a connecting rod is fixedly connected to the top of the annular block, the connecting rod being slidably disposed in the arc-shaped hole.

[0010] The annular block provides stable support for the second bevel gear, and its meshing structure with the first bevel gear enables synchronous transmission, ensuring that the four support plates are adjusted in a consistent manner and preventing the reaction cup from tilting. The arc-shaped hole limits the stroke of the connecting rod to prevent excessive rotation from damaging the components, while ensuring that the adjustment range of the support plate is adapted to the installation space of the coagulation analyzer, thus improving positioning accuracy.

[0011] Preferably, a horizontal plate is fixedly connected above the connecting rod, a telescopic rod is fixedly connected to one side above the horizontal plate, a pad is fixedly connected above the telescopic rod, a spring is fixedly connected above the horizontal plate, the spring is sleeved on the outside of the telescopic rod, and the upper part of the spring is fixedly connected to the lower part of the pad.

[0012] The telescopic rod prevents the pad from shifting, ensuring accurate positioning later; the spring can automatically reset after the pad is pulled, allowing the positioning rod to quickly align with the positioning slot without manual adjustment, simplifying the operation steps and improving the efficiency of loading, unloading, or adjusting the reaction cup.

[0013] Preferably, a positioning rod is fixedly connected to the lower part of the pad, and the lower part of the positioning rod extends through to the lower part of the horizontal plate, and the positioning rod is movably inserted into the positioning groove.

[0014] The positioning rod is movably inserted into the positioning slot. When the positioning rod is inserted into the positioning slot, it can lock the position of components such as the annular block and the lead screw, preventing the support plate from shifting due to vibration during reaction cup testing or handling, thus ensuring test repeatability.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model moves the pad upward by pulling it, which in turn stretches the spring and extends the telescopic rod, causing the positioning rod to disengage from the positioning groove. The horizontal plate is then held and rotated along the travel direction of the arc-shaped hole. The connecting rod drives the ring block to rotate. When the ring block rotates, the second bevel gear on its inner side rotates synchronously. Because the second bevel gear meshes with the four first bevel gears, it drives the four lead screws to rotate synchronously. When the lead screws rotate, the externally threaded slider moves radially along the rectangular hole under the limiting action of the guide rod, which drives the support plate to move. This ensures that the reaction cup can be accurately and quickly placed in the predetermined position each time, guaranteeing the repeatability and accuracy of the test.

[0017] 2. This utility model provides a clear point of application for the operator's fingers by creating a groove on one side of the support plate, thus achieving a stable and easy gripping and effectively preventing slippage. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1, by Figures 1-4This utility model relates to a coagulation analyzer reaction cup that is easy to handle and place. It includes a cup body 1, with a support mechanism 2 on the outside of the cup body 1. The support mechanism 2 includes an annular seat 201, which is fixedly sleeved on the outside of the cup body 1. An arc-shaped hole 507 is formed above the annular seat 201 to limit the rotational stroke of the support mechanism 2. Two positioning grooves 208 are formed above the annular seat 201, and four rectangular holes 211 arranged in a ring array are formed below the annular seat 201. Guide rods 212 are fixedly connected to the inner walls of the rectangular holes 211. A cavity 202 is formed inside the annular seat 201. The inner wall of 02 is rotatably connected to four lead screws 203 arranged in a ring array. The lead screws 203 are fixedly sleeved with a first bevel gear 204. The lead screws 203 are threadedly connected to a slider 210. The slider 210 is slidably disposed inside the rectangular hole 211 and sleeved on the outside of the guide rod 212. Through the mutual cooperation between the guide rod 212 and the rectangular hole 211, the slider 210 can be limited, which improves the stability of the slider 210 movement. A support plate 213 is fixedly connected to the bottom of the slider 210. A groove 214 is opened on one side of the support plate 213. The groove 214 can fit the gap between fingers for easy picking.

[0027] An annular block 205 is rotatably connected to the inner wall of cavity 202. A second bevel gear 206 is fixedly connected to one side of the annular block 205. The second bevel gear 206 meshes with four first bevel gears 204, and through the second bevel gear 206, it can drive the four first bevel gears 204 to rotate synchronously. A connecting rod 209 is fixedly connected above the annular block 205. The connecting rod 209 is slidably disposed in the arc-shaped hole 507. A horizontal plate 215 is fixedly connected above the connecting rod 209. A telescopic rod 216 is fixedly connected to one side above the horizontal plate 215. A pad 20 is fixedly connected above the telescopic rod 216. 7. A spring 219 is fixedly connected to the upper part of the horizontal plate 215. The spring 219 can provide a reset pressure to the telescopic rod 216. The spring 219 is sleeved on the outside of the telescopic rod 216. The upper part of the spring 219 is fixedly connected to the lower part of the pad 207. A positioning rod 218 is fixedly connected to the lower part of the pad 207. The lower part of the positioning rod 218 extends through to the lower part of the horizontal plate 215. The positioning rod 218 is movably inserted into the positioning groove 208. The insertion and cooperation between the positioning rod 218 and the positioning groove 208 locks the adjustment position of the support plate 213 to prevent the support from loosening due to vibration during detection or handling.

[0028] Working principle: In use, by pulling the pad 207 upward, the spring 219 is stretched and the telescopic rod 216 is extended, causing the positioning rod 218 to disengage from the positioning groove 208. The horizontal plate 215 is held and rotated along the stroke direction of the arc hole 507. The connecting rod 209 drives the ring block 205 to rotate. When the ring block 205 rotates, the second bevel gear 206 on its inner side rotates synchronously. Since the second bevel gear 206 meshes with the four first bevel gears 204, it drives the four lead screws 203 to rotate synchronously. When the lead screws 203 rotate, the externally threaded slider 210 moves radially along the rectangular hole 211 under the limiting action of the guide rod 212, which drives the support plate 213 to move, thus opening the support mechanism 2.
